Be sure to affix a label on only the correct location so
as not to cause malfunction of the VCR.

After use, please be sure to rewind the tape completely
(to prevent picture and sound distortion). Return it to
its case and store in upright position.

About moisture condensation

If the unit or tape is brought directly from a cold to a
warm location, moisture may condense inside or
outside the unit or tape. If you use the tape or video
heads in this condition, the tape may adhere to the
head drum, and the video heads or the tape may be
damaged, or malfunction may occur.
Moisture condensation is likely to occur under the
following conditions:
• The unit is brought from the cold outdoors to a warm
indoor location.
• The unit is brought from the air-conditioned indoors
to the hot outdoors.
• The unit is used in a place subject to cold currents
from an air conditioner.
When bringing the unit from a cold place to a warm
place or vice versa, put it in a plastic bag and seal the
bag tightly. After bringing it into the new place, leave
the bag on for about an hour, and remove the bag when
the air temperature inside it has reached the
temperature surrounding it.

Chapter 4 Maintenance and Troubleshooting
If moisture condensation occurred
You cannot operate the unit except to press Z EJECT.
If you insert a cassette, it is ejected automatically. If
this occurs, turn on the power, wait about an hour for
the moisture to evaporate.

Digital hours meter

The digital hours meter keeps cumulative counts of the
head drum rotation time and the number of
unthreading operations. These counts can be displayed
on the monitor screen. Use them as guidelines for
scheduling maintenance.
In general, consult your Sony dealer about necessary
periodic maintenance checks.
The digital hours meter has the following two display
modes and you can check them in the HOURS
METER menu (see page 34).
• DRUM ROTATION mode
The cumulative total hours of drum rotation with tape
threaded is displayed in 10-hour increments.
• THREADING mode
The cumulative number of tape unthreading operation
is displayed in 10-operation increments.
